Here,
Expenditures of A,B and C = 80%,85% and 75%.
So, Their savings will be
100-80 = 20%
100-85 = 15%
100-75 = 25%.
Now,
20% of A = 15% of B = 25% of C
i.e. A/5 = 3B/20 = C/4
A= 3B/4 ,C = 3B/5
And,
A+ B +C = 9400.
By putting values of A and C,
3B/4 + B + 3B/5 =9400
47B/20 = 9400
B = 4000.
So, Income of B = Rs 4000.
